<p>A resilient device for the lost motion coupling and centring of first (10) and second (12) coaxial rotary members by enabling limited relative angular movement thereof. The second rotary member (12) has a portion surrounding a portion of the first rotary member (10). At least one spring (14) is substantially coaxially arranged between said portions of the first (10) and second (12) rotary members. A first linking means is provided for co-operatively linking the spring (14) and the first member (10), and a second linking means is provided for co-operatively linking the spring (14) and the second member (12). Said first and second linking means hold the first member (10) in a centred position relative to the second member (12) by means of the spring (14). At least one of the first and second linking means allows limited relative angular movement of the spring (14). Said spring (14) comprises a substantially ring-shaped continuous portion completely surrounding the first member (10).</p> |
