I have a similar problem, but different. 

I would like not having the point after the the closing parenthesis in 

> Theorem 5 (Fundamental theorem of AbelianGroups).

to be typeset in bold.

Typsetting this point in bold goes against the tradition in typography which says the ponctuation has to use the same font as the preceding text. 

``Old manuals of style say that the punctuation after a word should be in the same font as that word.'' D. Knuth, The TeXBook, p. 14. 

I have looked in the definitions of amsthm.sty, but I could not a way of changing the font of this point.
