1. A method for adapting a steering torque for controlling a feedback actuator of a steer-by-wire motor vehicle steering system, the method comprising:
providing a basic steering torque;
providing a rack-force-based steering torque;
determining a difference between the basic steering torque and the rack-force-based steering torque; and
either
adapting the basic steering torque to the rack-force-based steering torque and transmitting a resulting steering torque to control the feedback actuator if the difference exceeds a predetermined limit value, or
transmitting the basic steering torque to control the feedback actuator if the difference is below the predetermined limit value.
