The invention relates to an actuating device (1) for displacing a control device (3), against a force in the opposing direction (2) to the displacemen t, comprising an operating element (7) in a device housing (4), which may be axially displaced, at least in the direction of displacement by means of a feed mechanism (6). In order to improve said actuating device such that it m ay be simply operated without any impairment in emergency, when, for example th e energy supply fails, or other problems occur, said actuating device comprise s an emergency actuator, which may be externally operated and which may be connected to the feed mechanism (5) by means of a directional coupling devic e. |
