1. A torsional vibration damper comprising:
an input part for introducing a torque;
two intermediate elements:
movement-coupled to the input part; and
each linearly movable towards and away from the other in a radial plane of the torsional vibration damper;
an energy storage element designed as a compression spring that acts on the intermediate elements;
an output part for discharging a vibration-damped torque:
movement-coupled to the intermediate elements; and
rotatable relative to the intermediate elements; and
an elastic or resilient compensation part provided between the output part and the intermediate elements for eliminating play of the intermediate elements relative to the output part in an axial direction.
