regex not working to replace numbers with enclosing brackets numbers

how can i replace 't1 w1 r2 (L2) d1 L12aa' with 't(1) w(1) r(2) (L(2)) d1 L(12)aa'

means replace every digit ot two after [twrL] only with the number with enclosing brackets

i've tryed this but its not working

regexprep('t1 w1 r2 (L2) d1 L12aa','([twLr])/(\d*/)','$1($2)')
