Yes:Adapt.course.get('displayTitle');
or:Adapt.course.get('title');
If you want the plain text version. For example, the code that applies the course title to the document (broswer window/tab title) uses the plain text version.
You can also include it in a handlebars template by putting {{import_adapt}}
in the .hbs file (usually at the top) then using {{{Adapt.course.displayTitle}}}
or {{Adapt.course.title}}
where you want to show it.
You can do something similar in the .json files as well, e.g. try adding {{import_adapt}}{{{Adapt.course.displayTitle}}}
into the body
of a text component.
BTW you haven't said what version of Adapt you're using, I've assumed it's fairly recent but if it's quite old (v2.x) then some of this won't work
