The hydraulic actuator comprises: a hydraulic input cylinder having an input piston; a hydraulic output cylinder, which is hydraulically coupled to the input cylinder; and a pressure-limiting valve, which limits the output cylinder with respect to pressure in dependence on the usability of a force on the input piston. The method is a method for operating such a hydraulic actuator, wherein the drive actuator is deflected with deflections having a deflection duration at a deflection frequency for the duration of an acting or a non-acting phase of the hydraulic actuator, wherein the deflection duration defines a movement stiffness of the hydraulic actuator and the deflection frequency defines the resulting deflection speed of the hydraulic actuator.

A coupling element is provided for an electric switching device wherein the coupling element includes a first switching contact for opening and closing an electric contact by a second switch contact. The coupling element has an oblong winding body having two ends that are opposite in the longitudinal direction of the longitudinal axis thereof, wherein the first switch contact is arranged on one end. The coupling element furthermore includes a rotation body through which the winding body extends and that is provided for coupling to a drive to carry out a rotation movement by the drive, wherein the rotation body includes two sides of which one faces one end (of the winding body and the other faces the other end of the winding body.
