I'm building a small wind turbine and I'm trying to find a way to make the metal rod where the propellers are rotate the axle of a small motor. The diameter of the rod is 1/4" and the diameter of the axle of the motor is about 2 to 3 millimeters. This is more or less the design of the turbine I'm trying to make. I know it says "coupling" there, but I have no idea what that actually is, and the pictures I've found seem to be all for bigger stuff. Any ideas are appreciated.
