phi=Torsional deflection(degrees)
T=Torque(in-#)
L=Length(in)
J=Polar Moment of Inertia(in^4)
G=Modulus of Rigidity(#/in^2)
You're measuring deflection of the shaft, right? Solve the equation to gain internal torque(T). Once torque is known and rpm is measured, you can solve for horsepower.
Is that how the device works?

Very cool...Love the idea. ![Cool](/forums/images/smilies/cool.gif)
Just curious, where did you obtain the torque vs deflection data for that particular shaft? Was it through measured testing? How will this apply to other such application(other drive systems)?
Just curious.
