The invention relates to a combined sensor device (100) for a motor vehicle, comprising a torque sensor unit (10) and a steering angle sensor unit (20), and a secondary rotor assembly (30) for a steering angle sensor unit (20) of such a sensor device (100), the steering angle sensor unit (20) has a main rotor (21) which can be connected to a shaft (11) for common rotation, a first secondary rotor (31), a first steering angle magnetic unit (32) which is assigned to the first secondary rotor (31) for generating a first steering angle magnetic field, and a first steering angle sensor unit (20) which is assigned to the first secondary rotor (31) in accordance with the main rotor (21). The first steering angle magnetic sensor (35) generates at least one first sensor signal according to the rotation angle. The sensor device (100, 200) further comprises a magnetic shielding unit (33, 43) having at least one flat magnetic shielding element (33) for at least partially shielding a torque sensor magnetic field of the to
