Abstract
Components such as turbine shafts are maintained coaxial with each other by a coupling ring. The coupling ring includes a body which is cylindrical when unstressed, and which has two arrays of projections each array engaging a respective cylindrical surface of recesses in the components. The body is flexible, and so is resiliently deformed by contact between the projections and the respective cylindrical surface. The projections of the two arrays are angularly out of phase with each other.
