Looking for a simpler way to construct a toroidal helix.

in General
Does anyone have a suggestion for a simpler/cleaner way to do this. It's a helical coil around a torus.
Since the inner radius is less than the outer radius simply building the helix on a cylinder is unsatisfactory (seePart _helix on torus_). For this attempt, I created a 15° pattern of hexagons and simulated a helix with a 3D Fit Spline defined by sequential vertices of the hexagons. The problem here is that there is no curvature at the vertices of the splines.
My process is in the tab labeled _toroidal helix_ in the linked document.
