Eric, IF PB Blaster doesn't work, you might try heat on the coupler. Get two pipe wrenches - shaft and coupler. Heat and twist. If that fails, use a gear puller or make one with a small piece of 1/4 inch thick metal, drill holes to match the coupler and a threaded center hole for a decent size bolt. Bolt the plate to the coupler and use the center bolt to push the shaft out.
