ABSTRACT:
The invention relates to a stabilising device (120) for an assembly which includes two shape memory alloy wires (104, 106) adapted to operate in conjunction. The stabilising device (120) includes a rocker plate (108) for attachment to each of the shape memory alloy wires; the rocker plate (108) is adapted to pivot when one shape memory alloy wire (104or106) is subjected to a stress greater than that to which the other shape memory alloy wire (106or104) is subjected, in order to reduce the stress on the first-mentioned shape memory alloy wire. The invention further relates to a fastener (60) including a stud (54) having a locking cavity (56), an aperture (58) adapted to receive the stud (54), a locking means (teeth) (62) adapted to engage the locking cavity (56), a shuttle (66) rotatable by a rotating means including material adapted to contract when activated and a plug (87) slidable within the shuttle (66) to close off the aperture (58) when not occupied by the stud (54). The shuttle (66) is rotatable by the rotating means between a locking position, in which the locking means (teeth) (62) engages the locking cavity (56), and an unlocking position in which the locking means (teeth) (62) does not engage the locking cavity (56). The plug (87) can help to prevent contamination of the fastener (60).
