Abstract
A flexible coupling for transmitting torque between parts of a transmission shaft system comprises a tubular section of continuous-fibre-reinforced composite material which has been modified to form a living hinge section with reduced bending stiffness to allow flexion of the tubular section. The tubular section may be modified through the provision of a pattern of formations within the living hinge section. The formations may be in the form of apertures and/or recesses in the continuous-fibre-reinforced composite material to create a plurality of living hinges in the material between, in particular slots and/or grooves.
