The name before the "{" is just used for display. If "bridgeporttool" 
were clearer to you than just "tool" you could change it.

However, The real problem is that the term module needs a better 
definition here.  The diagapplet was designed for module to be an 
instance of the class NML_MODULE, or any class derived from NML_MODULE. 
Each NML_MODULE creates two NML buffers that can be used to control it 
(command buffer) and monitor it (status buffer). A single program can 
create and run multiple modules so simio runs 5 which I named tool, aux, 
spindle, coolant, and lube. bridgeporttask doesn't actually create any 
but it does use NML command and status buffers so it looks to the rest 
of the world like it is close enough, so it is represented by the task 
module in the .cfg file.  I ussually think of emcmotsim as having 2 
modules trajectory planning and servo but neither directly uses NML for 
command or status so nothing from emcmotsim is direcly visible in 
diagapplet or the .cfg file. However in the status display for the task 
module  in the details view of diagapplet is section for motion which is 
taken fairly directly from emcmotsim. emcsvr and emcsh are  utility 
program without command and status buffers of their own so they don't 
show up either. However, if emcsvr is not running diagapplet won't be 
able to connect. (The connected checkbox will stay red when clicked on 
and none of the data in the display will change.) You can tell what the 
last command emcsh (which is not visible in diagapplet) sent by looking
at the last command recieved by the task module.
