The details in that link are a bit excessive, but you get the idea. You want the surface of the shaft and the surface of the prop to have as much surface area contact as possible. In a pinch, I'll spin the prop on the shaft a bunch before putting in the key and nut for a final installation. Clearly not as good, but it might help.
