Abstract
Apparatus to screw heavy lids very sensitively on thick-walled receptacles n order to avoid damaging the threads includes a stationary member centered on the receptacle and of an axially movable platform which is guided such that torques can be transmitted and the common axis always remains the same. Resilient members of adjustable length transmit mass forces in vertical direction exactly on the stationary member and prevent additional forces from acting on the flanks of the threads.
