Zusammenfassung:An apparatus that controls the position of a component of a mechanical system, such as an adjustable concave in a combine harvester, while at the same time exhibiting a safety function that is reversible without requiring a long downtime of the combine. The apparatus includes a control part and an auxiliary part, both pivotable about the same axis, and a force transmission part to maintain these two parts in an assembled state by a spring force, as long as the component is subjected to forces below a given limit. When the forces exceed the limit, the auxiliary part and the control part are configured to become separated in such a manner that they can be reassembled by the intervention of an actuator. The safety function of the apparatus resembles the operation of a shear bolt.
