1. A device, comprising:
a spindle for a machine tool;
a driver ring mounted and displaceably fixed on the spindle such that the driver ring is displaceable along a rotational axis of the spindle;
a tool holder; and
a spring element which acts between the spindle and the driver ring and presses the driver ring against a plate of the tool holder,
wherein the spindle and the tool holder have matching faces which are designed to form a frictionally engaged connection when assembled,
wherein, when assembled, opposing faces of the tool holder and the driver ring have matching contours, so that the driver ring can engage on the tool holder.
