Back end (larger diameter) is heat shrink fit onto the base of the shaft so once cools off, it's dead grip there. I was told that recommended pre-heat temp is up to 400'F.
This attachment is enough because there is no real axial force trying to take the hub off the shaft (other than just vehicle motion). If one still worried, a large washer in front of the adapter held by a bolt going into the M6 threaded hole in the shaft center (made for this purpose) will provide piece of mind. I made 1 mm recess in front flange for this washer. If special bolt is machined similar to one seen on http://www.metricmind.com/ac_honda/images/coupler4.jpg then mounted adapter will be flush with the shaft end as here http://www.metricmind.com/ac_honda/images/coupler5.jpg. Adapters are made of quenched tempered 4142 steel. Of course, standard taper lock is still required.
