A method for detecting damage done to a clutch having at least two components that transfer torque by frictional engagement comprises the following steps: determining the friction power L introduced into the friction surfaces of the components by slippage between the torque-transferring components, calculating an individual damage value ESW=f(L,t), wherein t denotes time, and rating the clutch as damaged when ESW exceeds a predetermined value.

Actuation devices are disclosed for a pressure-closed clutch where the position of an actuation member is acquired by an incremental sensor. In an embodiment of the actuation device, the signal of the incremental sensor is acquired in case of a sudden change in the power consumption of an actuator and is used as a new reference signal. In another embodiment, the actuation member, while the spindle is rotating, is moved by a recovery spring during the closing of the clutch against a stop and the signal of the incremental sensor upon the attainment of said stop is used as a reference signal.
