For the selective rotational coupling of two coaxial shafts (14, 24) offset relative to one another in the axial direction, a coupling device is provided which can be switched between a first operating state, in which both shafts (14, 24) are coupled to one another positively, and a second operating state, in which a driver part (46) on which a manual actuating element (54) engages non-positively, is coupled positively to the load-side shaft (24) and the input-side shaft (14) is coupled only frictionally to the driver part (46). For manual actuation, essentially only the load torque has to be applied to the manual actuating element. <IMAGE>
