A method sets a predefined position of a clutch actuator comprising a friction spring element. An activation path of the clutch actuator that actuates the clutch is predefined by a coupling torque via a coupling characteristic curve, wherein the predefined position (zo, zu) to be assumed by the clutch actuator is set by a closed-loop controller. To enable the predefined position of the clutch actuator to be set precisely without using additional energy, the predefined position (zo, zu) is corrected by a turning back value (ro, ru) of the friction spring element and the corrected position (zo+ro; zu−ru) of the clutch actuator is approached by the closed-loop controller. After reaching the corrected position (zo+ro; zu−ru) the closed-loop controller is switched off by dissipating the potential energy stored in the friction spring element.
