An actuator device (1) for generating a longitudinal positioning movement to engage a shift element includes an actuator housing (2) and an electric motor (3). The electric motor (3) has a stator (4) and a rotor (5), the stator (4) being stationarily fixed at the housing (2), and the rotor (5) being rotatable relative to the stator (4) and rotationally fixed to a rotor carrier (6) supported relative to the housing (2) via a fixed bearing (7). The actuator device (1) further includes a threaded drive (8) having a nut (9) and a threaded spindle (10), with the nut (9) being rotationally driveable and axially fixed, and the threaded spindle (10) being axially displaceable along the threaded nut (9) and secured against rotation. The threaded nut (9) is rotationally fixed to the rotor carrier (6) and is at least partially radially within the fixed bearing (7).
