摘要

The device has a drive shaft (2) and an output shaft (3) mounted to rotate about drive (21) and output (31) axes, a loop spring (4) that holds the shafts engaged in a coupled state and a lock (5) with which the clutch can be changed to a decoupled state. The device has an arrangement (6) for minimizing vibrations of the clutch in the disengaged state. A definable contact region of the drive and/or output shaft has a non-circular cross-section.
