The invention discloses a power tool comprising a clutch having a first clutch element and a second clutch element which are seated for rotation one relative to the other and between which a torque can be transmitted. The clutch comprises an actuating element engaging at least one of the first and second clutch elements for moving the clutch between an engaged position for effecting power transmission from a drive shaft to an output shaft, and between a released position wherein there is no power transmission to said output shaft. The actuating element comprises a nanotube actuator.

A catch for two objects moveable in relation to one another, in particular a door catch, includes a cylinder, which is operatively connected to a first object, a friction surface carrier, which is operatively connected to a second object, a friction element for creating a frictional grip between the cylinder and the friction surface carrier through an energy input. The friction element being connected to an electrical voltage supply device, wherein a change in the volume of the friction element, which constitutes an actuating movement of the friction element in relation to the friction surface, occurs as a function of the voltage applied to the friction element.
