An actuator assembly has a ball screw drive, having a ball screw spindle rotatably mounted about a spindle axis and on which a spindle nut is received, wherein at least one thread track is formed on an outer circumferential surface of the ball screw spindle, which track extends over less than 360° of the circumference of the ball screw spindle. A ball return is arranged on the outer circumferential surface for each thread track and connects a beginning and an end of the thread track to one another. A ball race for the balls is formed in a separate insert, which is inserted into a depression arranged in the outer circumferential surface. To produce the ball screw spindle, a thread is introduced into the outer circumferential surface of the ball screw spindle and at least one depression is introduced into the outer circumferential surface. The depression defines the beginning and end of a thread track. The insert is inserted into the depression in such a way that its ball race adjoins the beginning and the end of the thread track.
