Abstract
A coupling for use in a transmission system and between coaxial rotary members which are arranged for driving engagement through axially engaging teeth thereon, one of said members being connected, directly or indirectly by helical splines to a further part such that in normal rotation, the said one member has a force exerted upon it tending to separate the teeth, such force being resisted by a fusible element which will melt when temperature rises above a predetermined value, melting of said element permitting axial movement of said one member relatively to said further part, through the splines to permit disengagement of the teeth, bearings supporting said further part, being substantially free from axial loading and spring means being provided for preventing re-engagement of the teeth after the element has melted.
