DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 diagrammatically shows one embodiment of the claimed coupling 30 in an oblique view. The coupling 30 comprises two multiple disk assemblies 20 which are fastened releasably to an intermediate piece 10 on both sides, that is to say on a drive side 31 and an output side 33. A connecting flange 40 is arranged in each case on the multiple disk assemblies 20 on a drive side 31 and an output side 33. Drive power 25 is fed about a main rotational axis 15 of the coupling 30 via a drive-side connecting flange 42. The drive power 25 is discharged from the coupling 30, furthermore, via an output-side connecting flange 44. The drive-side and the output-side connecting flange 42, 44 are likewise connected releasably in each case to a multiple disk assembly 20. The intermediate piece 20 comprises a circumferential main body 19 which is of substantially tubular configuration. The main body 19 is configured in one piece with a drive-side flange 12 and an output-side flange 14 which are also in each case of circumferential configuration. The drive-side and the output-side flange 12, 14 of the intermediate piece 10 in each case have recesses 17 which are configured for receiving releasable fastening means 24, Via the fastening means 24 in the recesses 17 in the drive-side and output-side flange 12, 14, the latter are connected releasably to the respective multiple disk assembly 20.

Longitudinal webs 16 which are of substantially rib-shaped configuration are also molded in one piece on the circumferential main body 19 of the intermediate piece 10. The longitudinal webs 16 extend substantially parallel to the main rotational axis 15 and in each case establish a load-transmitting connection between the drive-side flange 12 and the output-side flange 14. As a result, a plurality of pockets 18 are configured in each case between two longitudinal webs 16, the drive-side flange 12, the output-side flange 14 and the circumferential main body 19. Accordingly, the pockets 18 are arranged circumferentially on the intermediate piece 10. The longitudinal webs 16 represent a reinforcement against torsional loading of the intermediate piece 10. As a result of the pockets 18, the intermediate piece 10 is relatively light and at the same time rigid against torsional loads between the drive-side and the output-side flange 12, 14. The fastening means 24 which are to be mounted for releasable fastening to one of the multiple disk assemblies 20 can be inserted into the pockets 18 in a radial direction 37 and can be mounted substantially by way of an axial movement, that is to say along the main rotational axis 15. Falling into the interior of the intermediate piece 10 which is difficult to access is thus avoided. Mounting of the coupling 30 is simplified and accelerated as a result. Furthermore, the drive-side and the output-side flange 12, 14 have a first wall thickness 41 in a region which is free from fastening means 24, and have a second wall thickness 43 in a region with a releasable fastening means 24. Here, the first wall thickness 41 is smaller than the second wall thickness 43. The second wall thickness 43 therefore provides a rigid receiving means for a fastening means 24 which establishes a releasable connection between the intermediate piece 10 and one of the multiple disk assemblies 20. The higher the second wall thickness 43, the greater the load-bearing capability of the drive-side and output-side flange 12, 14 in this region, for receiving the load which is brought about by virtue of the fact that drive power 25 which acts on the intermediate piece 10 is converted into a tensile load in the respective multiple disk assembly 20. Those regions of the drive-side and output-side flange 12, 14 which are free from releasable fastening means 24 are of weight-saving configuration as a result of the first wall thickness 41. As a result of the alternating arrangement of regions with the first and the second wall thickness 41, 43 on the drive-side and output-side flange 12, 14 of the intermediate piece 10, the latter is configured in a manner which is suitable for the load, which permits a higher material utilization.

In a manner which corresponds to the drive-side and output-side flange 12, 14 of the intermediate piece 10, the drive-side connecting flange 42 and the output-side connecting flange 44 are also configured with regions which have a first and a second wall thickness 51, 53 in an alternating manner. The drive-side and output-side connecting flange 42, 44 are configured in each case with recesses 17 for receiving releasable fastening means 24. Via the fastening means 24 which are received in the drive-side and output-side connecting flange 42, 44, the latter are connected in each case to one of the multiple disk assemblies 20. The releasable fastening means 24 which are received in the connecting flanges 42, 44 and in the flanges 12, 14 of the intermediate piece 10 are arranged so as to alternate circumferentially, which results in a load distribution which is suitable for the load for the multiple disk assemblies 20. A circulating direction is illustrated in FIG. 1 by the arrow 35. Regions of the connecting flanges 42, 44 with a first wall thickness 51 are arranged opposite regions of a flange 12, 14 of the intermediate piece 10 which have the second wall thickness 43. In a corresponding manner, regions of the connecting flanges 42, 44 with the second wall thickness 53 are arranged opposite regions of a flange 12, 14 of the intermediate piece
