Assuming that the nodes are shared between solid and shell (so using shared topology), then the translational dof are shared, and hence these translations will be transferred - rotations are not transferred across there though, since 3D solid elements do not have rotational dof. To show that, say we connect the two (shared nodes along edge) along an edge, then the shell is hinged about that edge and is allowed to 'hinge/rotate' about the global Z axis as shown below.

Now another way to connect them than just sharing nodes which could lead to the above behaviour is to couple them (solid and shells) via contacts which can be common, see here:
See the help manual for a guide on how to do that:

Or search for Modelling Shell-Solid Assembly in help.

For the above example we do not have the hinge anymore (connected with bonded MPC, the face of the solid to the surface edge):

All the best
