Abstract
The invention relates to a clutch of the kind comprising a coupling element (33) which acts like a piston, and a clutch plate coupled with the coupling element to permit the latter to be driven in rotation. In order to drive the coupling element (33) positively in rotation in both directions, the clutch plate (35) has in combination two groups of tongue or strip portions (48T, 48R), which extend in opposite circumferential directions and which are associated in the sense that each strip portion of one group is paired with a strip portion of the other group, a strip portion (48T) of the first group being continuous with a strip portion (48R) of the second group.
