Actuator arrangement for a drive train, which has at least one friction clutch for transmitting drive torque and has a transmission. The friction clutch can be actuated by means of a hydraulic clutch cylinder, which is connected directly to a pump port of a pump driven by an electric motor in order to actuate the friction clutch, such that the friction clutch can be actuated by varying the speed of the pump. The actuator arrangement has a parking lock actuator device for actuating a parking lock arrangement of the drive train. The parking lock actuator device has at least one hydraulic parking lock cylinder, which can be connected to the pump, such that the parking lock arrangement can be actuated by varying at least one of the direction of rotation or the speed of the pump.
