Example steering wheel actuator device for a steer-by-wire steering system of a vehicle are disclosed herein. An example steering wheel actuator device includes at least one steering wheel angle measuring device to measure a steering wheel angle of a steering wheel, a motor device to generate a motor torque counteracting a driver torque applied to the steering wheel, a control device, and an electrical energy source that supplies the steering wheel actuator device with electrical energy. The actuator device has an electrical energy storage device is configured to supply at least one steering wheel angle measuring device with stored electrical energy if the steering wheel actuator device is not supplied with electrical energy by the electrical energy source. The electrical energy storage device can preferably be charged with electrical energy generated by the motor device if the applied driver torque surpasses the motor torque.
