摘要

A transmission system comprises an annular input member adapted to be keyed at least circumferentially to a first shaft. It has a generally cylindrical axial wall. A movement take-up device within this cylindrical wall has at least one protected mild steel lug by which it is keyed axially and circumferentially to the cylindrical wall and by which it is adapted to be at least circumferentially keyed to a second shaft. The movement take-up device also comprises an input part to which one end of this lug is welded, the other end of the lug being fixed to the cylindrical wall.
