Coupling

A linkage member for a load path with a load being applied in a direction F1 the linkage member comprising:

• a first elongate link element pivotally attached at a first pivot point to a first load path component and pivotally attached at a second pivot point to a second elongate link element,
• wherein the second elongate link element is pivotally attached at a third pivot point to a second load component;
• wherein the first and third pivot points are moveable relative to each other in a direction substantially parallel to the direction F1 to create a rotation of the second pivot point about the first pivot point;
• the linkage member further comprising an electromagnet arranged to apply a secondary load to the linkage member in a direction F2 which is substantially orthogonal to the direction F1 to oppose movement of the first and third pivot points away from each other.
