A hybrid module (10) for a drivetrain of a motor vehicle is provided, having a separating clutch (14) for coupling an input-side drive shaft, in particular crankshaft, of an internal combustion enginefor mechanically driving the motor vehicle to an output-side intermediate shaft (12), in particular rotor shaft, of an electric machine for electrically driving the motor vehicle, and having an actuating device (16) which is co-rotatable with the drive shaft or with the intermediate shaft (12) and which serves for actuating the separating clutch (14), wherein the actuating device (16) has a pressure chamber (30) which is connectable to a pressure source and which serves for providing a hydraulic actuating pressure for actuating the separating clutch (14), which hydraulic actuating pressure can be built up by means of a hydraulic medium, and said actuating device has a compensation device (42) for at least partially compensating a change in pressure in the pressure chamber (30) caused by centrifugal forces acting on the hydraulic medium. A rotational-speed-dependent change in pressure in the pressure chamber (30) caused by the co-rotating actuating device (16) can be compensated by means of the compensation device (42), such that a precise actuation of a separating clutch (14) in a hybrid module (12), and a prevention of unnecessary loads, are made possible.
