Abstract: A helical gearing for driving an adjusting element, which may be an actuator or a piston of a piston-cylinder unit, is driven by an electric motor. The adjusting element may be moved along an axis. The drive apparatus has a rotor, or a translator rotatably mounted in a housing by a bearing and fixedly connected to the input of or formed integrally with the helical gearing. The output of the helical gearing is connected to or formed integrally with the adjusting element. An anti-twist means may prevent the adjusting element from twisting in the circumferential direction about the axis. The helical gearing and/or at least part of the adjusting element is/are formed to be transversely elastic to the axis of rotation, at least in one region.
