A limited torque, positive drive transmitting arrangement employs a leaf chain and a fluted pulley which co-operates therewith. The positive drive is transmitted via engagement of the leaf chain link edges with the specially formed pulley flutes, and the leaf chain is modified to ensure that the consequential loading of the link edges and any resulting damage thereto is prevented from interfering with the proper articulation of the chain in passing round the pulley.
