  In this work, the role which three-dimensional shaping plays in the
generation of rotational transform in toroidal magnetically confinement devices
is explored. The susceptance matrix as defined by Strand & Houlberg (2001) is
presented and compared to simulations of three dimensional MHD equilibria. The
dependence of the edge rotational transform on axisymmetric shaping is briefly
explored. It is then shown how simple three dimensional shaping can drive
rotational transform in a simply shaped stellarator. It is found that modes
with high poloidal mode number drive edge transform with little effect on the
core, while modes with poloidal mode m < 2 drive both edge and core rotational
transforms. This work concludes with a discussion of the non-linearity of the
three dimensional shape space as defined in terms of magnetic symmetry.
