How to set an arbitrary name for the __str__ column in the admin panel?

Question

Django

In admin.py :

class DeviceAdmin(admin.ModelAdmin):
    list_display = ('__str__', 'category', 'owner_id')

For the __str__ column, I get the name of the class (DEVICE). And you need something verbose_name, which are written in the fields of models in models.py , i.e. set an arbitrary field/column name.
Tell me how it's done?
PS Is it necessary to register this class in admin.py, and then pass it to admin.site.register(Device, DeviceAdmin), or can it somehow be done directly in models.py?
