Abstract
The invention relates to a control drive, in particular a spindle drive for adjusting a swivelable vehicle flap, comprising a housing (2), a spindle rod (3) that is rotatably mounted in the housing (2), a first coupling element (5) for driving a rotational movement of the spindle rod (3), and a torque-limiting device (6) arranged between the first coupling element (5) and the spindle rod (3) for limiting the torque transmitted from the first coupling element (5) to the spindle rod (3), comprising an adapter sleeve (8) arranged at a first end (3a) of the spindle rod (3) in a rotationally fixed manner, and a first tolerance element (13) arranged between the spindle rod (3) and the first coupling element (5). According to the invention, a control drive is provided, which is designed such that it is compact and can be economically produced, in such a way that the first tolerance element (13) is rotationally fixed to one of the first coupling element (5) and the adapter sleeve (8).
