Continuum coupling will force all slave nodes to strictly remain fixed with respect to rotation, and only allow rotation? Does structural not do the same?
 
Continuum coupling constraint couples motion of the reference node to the average translation of the coupling nodes. It distributes the forces and moments at the reference node as the coupling nodes forces only.

Structural coupling constraint couples the motion of the reference node to the translation and rotation of the coupling nodes. It distributes the forces and moments at the reference node as the coupling nodes forces and moments.
