We did this last year with mixed results. We basically made an keyed aluminum cylinder that fit inside of the octagon. We then used a hose clamp to keep the plastic teeth tight around the aluminum cylinder.
Here is our old CAD from last year,

If you want to see pictures, our gallery has many different pictures.
I would not suggest this approach for a drive system unless you have a more reliable way of connecting to the plastic octagon. A hose clamp eventually gets lose and then your shaft will be free-spinning.
