1. A ball screw drive for a vehicle steering system, the ball screw drive comprising:
a nut configured to receive torque from a power transmission drive, the nut having internal threads, and external threads being provided on the nut;
a threaded spindle having a spindle thread, the threaded spindle being drivable by the internal threads of the nut such that rotary motion of the nut is translated into linear motion of the threaded spindle; and
a rotational angle sensor having a sensor gear rotatably driven by the external threads of the nut, the rotational angle sensor is configured to generate an electric signal based on a rotational position of the sensor gear;
wherein the nut is monolithically formed with the internal threads and the external threads.
