I have used a heat gun successfully to loosen several different types of epoxy, including 5min araldite...just takes some care...go slowly and rotate the section of shaft evenly to spread the heat progressively and prevent the sort of delam problem you described. When it is just too hot to touch comfortably it should release when you twist it. Helps to have another pair of strong hands or pad up a vise to hold the handle against the twist. Go sloooowly.
EDit:
Tip - assuming you get a result and get the handle out cleanly, don't use epoxy to glue it back in. Use hot glue (Bostik or similar). Holds plenty strong enough and is much much easier to remove with heat if you need to go through the process again.
this is the way. done it over a dozen times. slowly is the key. don't get the handle and shaft too hot. the glue will break down.
even if you let the shaft and handle cool a touch before twisting.
make sure you heat all the glue areas and not just blast away at the top of shaft and work the handle too much.
you shouldn't need great force to twist- heat again slooooooowly
