Assembly including a flexible coupling

An assembly comprising:

• a first rotating component and a second rotating component, each including, at its end, three equiangularly spaced mounting fingers;
• and
• a flexible coupling comprising:
• a flexible torque disc having a first plurality of fixing points whereby it is mounted upon the mounting fingers of the first rotatable component, and a second plurality of fixing points whereby it is mounted upon the mounting fingers of the second rotatable component, the second fixing points each being located midway between a respective pair of the first fixing points;
• an annular support ring sandwiched between the flexible torque disc and the second rotating component, and
• mounting elements whereby the flexible torque disc is secured to the support ring, the mounting elements restricting deflection of the flexible torque disc relative to the support ring, wherein the mounting elements further serve to secure the first fixing points of the flexible torque disc to the first rotatable component;
• wherein the mounting elements each comprise a bush attached to a respective first fixing point of the flexible torque disc, the bush extending through an opening provided in the support ring, the bush defining a stop engageable with the support ring to limit movement of the part of the flexible torque disc adjacent the bush away from the support ring.
