Yes, it depends on the shell in question.
The above is for Bash. 
It works when Emacs is invoked "by hand" but not if it was 
started in  a shell script. It seems the command

  returnvalue='This is the return value.'

is executed after the script has finished (as the next
"keyboard input").

Within the script you can read in the "next keyboard input" 
into a variable. 

The following script seems to do what you want:

  #!/bin/bash

  /opt/emacs/23.0.60/bin/emacs -Q -nw -l ke.el
  read myval
  echo "myval is set to: '$myval'"
