<p num="1"><br/>The invention relates to a stabilising device (120) for an <br/>assembly which includes two shape memory alloy wires (104, <br/>106) adapted to operate in conjunction. The stabilising <br/>device (120) includes a rocker plate (108) for attachment to <br/>each of the shape memory alloy wires; the rocker plate (108) <br/>is adapted to pivot when one shape memory alloy wire (104 or <br/>106) is subjected to a stress greater than that to which the <br/>other shape memory alloy wire (106 or 104) is subjected, in <br/>order to reduce the stress on the first-mentioned shape <br/>memory alloy wire. The invention further relates to a <br/>fastener (60) including a stud (54) having a locking cavity <br/>(56), an aperture (58) adapted to receive the stud (54), a <br/>locking means (teeth) (62) adapted to engage the locking <br/>cavity (56), a shuttle (66) rotatable by a rotating means <br/>including material adapted to contract when activated and a <br/>plug (87) slidable within the shuttle (66) to close off the <br/>aperture (58) when not occupied by the stud (54). The<br/>shuttle (66) is rotatable by the rotating means between a <br/>locking position, in which the locking means (teeth) (62) <br/>engages the locking cavity (56), and an unlocking position in <br/>which the locking means (teeth) (62) does not engage the <br/>locking cavity (56). The plug (87) can help to prevent <br/>contamination of the fastener (60).<br/>
