Screwing heavy lids (4) to thin-walled containers (5) must be undertaken with a delicate touch in order to avoid damaging the threads (16, 17). A device for screwing consists of a stationary part (1), which is centred on the container (5), and of an axially moveable platform (2) which is guided such that torques can be transmitted and the common axis (12) is always maintained. In the vertical direction, resilient elements (7) of variable length exactly transmit the weight forces onto the stationary part (1) and prevent additional forces on the thread flanks. ……
