Actuator assembly

The invention relates to an actuator device for a brake, in particular an electric parking brake or electromechanical service brake with a brake pad adjustment unit (20) that can be driven by the actuator arrangement (10). The actuator arrangement has a modular design and comprises the following components: - an electric motor (40), - a transmission unit (50) seated in a housing, which is coupled with the electric motor (40) and is in operative connection on the output side with the brake pad adjustment unit (20), - fastening means (60) for fastening the actuator arrangement (10) to the brake caliper (30) or to the brake pad adjustment unit (20), - a plug receptacle (71) for a connecting plug of an electrical connection unit (70), which is electrically connected to the electric motor (40), - the electric motor (40) is at least partially surrounded by a surrounding housing (80), to which the plug receptacle (71) is integrally formed and/or - the fastening means (60) are designed as a separate replacement part, provided with fastening openings (63) and are secured in a rotationally fixed manner to the actuator arrangement (10).
