A form- and/or force-fit connection between the motor and the gearbox is established by screwing together a motor- or gearbox-side first component and the respective motor- or gearbox-side second component. Alternately, an interference fit can be established between these two components by way of an axial lock that includes a lug, which formed on the first component, that is deformed by a caulking tool into a recess formed on the second component.

A method of assembling a hinge comprising a first gear having one or more first teeth, a second gear having one or more second teeth and an area with no teeth, and a cover configured to attach the first gear to the second gear comprises moving the first gear into the cover and moving the second gear having the area with no teeth at least partially into the cover without engagement of the one or more first teeth and the one or more second teeth.
