An actuating device for a coupling/braking device is provided with at least one actuating piston that is axially slidable relative to a shaft and, in an actuating state, exerts an axially acting contact pressure on coupling/braking parts of the coupling/braking device. At least one control piston is provided that axially displaces the at least one actuating piston into the actuating position. A coating is provided in a contact region between the actuating piston and the control piston, wherein the coating is disposed at the actuating piston or at the control piston or at both the actuating piston and the control piston. The actuating piston can also be designed as a control piston that interacts immediately with the coupling/braking parts of the coupling/braking device.

A disc pack coupling for torque transmission between shafts has coupling discs. A locking unit is provided that maintains a contact pressure acting on the coupling discs when the disc pack coupling is closed. The locking unit has a locking part, a guide part, an actuating element, and a pressure element. The guide part is non-rotatably and non-displaceably arranged in relation to a first shaft. The locking part has a locking part axis and is rotatable about and displaceable axially relative to the locking part axis. Locking part and guide part are provided with interacting control surfaces positioned at a slant to a rotational direction of the locking part. The control surfaces are provided to move the locking part into a first and a second stop position. In the first stop position, the locking part maintains the contact pressure on the coupling discs.
