Claim Text:
1. A device for the application of a preload between two members, said device comprising: an activating member, a datum member, a locking member, at least one structural element positioned to secure the datum member relative to one of said two members, the activating member being moveable in an activating direction relative to the datum member, the activating member and the datum member including engagement zones which engage the locking member so as to cause, in response to movement of the activating member in the activating direction, a lateral movement of the locking member, said lateral movement having a component, parallel to the activating direction, which is substantially smaller than the movement of the activating member, and a support member which is positioned such that movement of the activating member in the activating direction causes the support member to be moved laterally and to abut and support the locking member against the engagement zone of the datum member.
