Yes, with an adams rite cam. Usually though, on the single cyl, the
thumb turn is attached with screws like most other deadbolts.
Apparently in ths case, someone converted a double cyl to a single cyl
by replaceing the inside cyl woth a mortise thumb turn (quite common).
To the original poster; You'll need an extra long allen wrench to reach
the set screw(s). Most standard ones that size are too short. This is
why all the deadbolts come with one in the box. I've got a shitload of
them laying around.
If you need one email me with your address and I'll be happy to mail you
one.
