Assuming it’s intact, the old shaft can be removed by heating the hosel with a heat gun, or a propane torch if you’re really careful. You need to heat the epoxy holding the old shaft to its failure temperature, which is typically somewhat above the boiling point of water. It works best if you can keep a constant force and/or torque on the shaft while heating, so the failure will be observed immediately.
If the shaft is broken off, you might be able to grip it with locking pliers. If it’s flush with the top of the hosel, something similar to a screw extractor can be used to get a grip on it.
