A drive coupling 10 has an outer plate 12 and an inner plate 14. Inner plate 14 is positioned within the inner periphery 16 of outer plate 12. The inner plate 14 includes a plurality of outwardly extending projections 18. The inner periphery 22 of outer plate 12 includes a plurality of recesses 24. The drive coupling 10 further comprises a plurality of compression springs 28 arranged between respective projections 18 of inner plate 14 and the respective side wall of the recess 24 of outer plate 12. A first retaining plate 42 is positioned by passing it over shaft 32. A spacer ring 48 is positioned such that it abuts one side of the inner plate 14. A second retaining plate 50 is located on the other of the inner and outer plates. Bolts 56 are used to hold the retaining plates 42 and 50 together. The drive coupling 10 is designed to carry the entire rated torque requirement of the unit on the compression springs, thus providing a continual cushioning action to the drive line whilst allowing a maximum angular movement if an obstruction is encountered.
